The Chemistry set is unlocked after Chemistry 1. It is located in Jimmy's room in the Boys' Dorm by the window. With the set, Jimmy can make a variety of weapons including firecrackers, stink bombs and itching powder. He can only use it once a day until Chemistry 5 is passed.
It is spotted by its smoke, fire and bright color, but before Chemistry 5 is passed, when you use it, it loses its color and stops smoking until the next morning when it becomes usable again. Starting at Chapter 4, if you have a bottle rocket launcher with spent ammo, the Chemistry set can be used to make more rockets. The following rewards are unlocked with each Chemistry class passed.
|Chemistry 1||Get Fire Crackers from your chemistry set|
|Chemistry 2||Get Stink Bombs from your chemistry set|
|Chemistry 3||Get Itching Powder from your chemistry set|
|Chemistry 4||Get full inventory of items instead of half|
|Chemistry 5||Use the chemistry set as many times per day as you want|
